The radius of the disk is R, and the mass of the disk is M. Using the parallel axis theorem and theequation for the moment of inertia of a disk about its central axis developed in the previous example, Eq. (8), the moment of inertia of the disk about the specified axis is Fig.
Short Circuits. Short circuits are the second most common reason for breaker tripping and are a more serious concern. Short circuits occur when the black hot wires inside your electrical service panel come in contact with either other hot wires or neutral wires.
Reasons for Shifts. The short-run aggregate supply curve is affected by production costs including taxes, subsidies, price of labor (wages), and the price of raw materials. All of these factors will cause the short-run curve to shift. When there are changes in the quality and quantity of labor and capital the changes affect both the short-run and long-run supply curves. The long-run aggregate supply curve is affected by events that change the potential output of the economy.
